PIPE-MAKING MACHINE.

Patented July 5, 1921.

T 0 all an 710m it may concern Be it known that we, Gnonen J. OLSEN andFRANK VVATERIIELD, both citizens of the 'United States, the formerresiding at (lolton, in the county of San Bernardino and State ofCalifornia, and the latter residing to produce a machine of thecharacter described, of simple form and construction. in which the pipeproduced is provided with a glazed finish on the interior of the pipe.

Another object of our invention is to produce a machine of the characterdescribed whereby a suspended core is moved vertically through a mold,and during such vertical travel is both reciprocated' and'revolved, themechanism for producing such movements being of simple form and construction and arranged above the mold.

- Another object of our invention is to produce a machine of the classdescribed in which the core moves upwardly through the mold during themaking of the pipe, and means provided for wetting the portion of thecore below the mold as it enters the mold.

Other objects and advantages will appear hereinafter from the followingdescription and the drawings.

Referring to the drawings, which are for illustrative purposes only,

The arm 130 is elastically held against the step 132 by means of coiledsprings 1e5, one end of said springs being secured to the fork 135 andthe other ends secured to bars 146 mounted on the ring 123. Thisconstruction is such that when the arm' 130 is moved over the center ashereinafter described the springs quickly throw the clutch in or out thecase may be. The springs 1 1%) have the further function of holding theclutch either in or out as the arm is held by the soringsin eitherextreme position.

The lower end of the rod 136 is rigidly mounted in a bracket 141-7secured to the standard 421, and at its upper end the rod is secured tothe cross bar 82. The squared upper end 128 of the shaft 72 extendsfreely through the cross bar 82 and through a bushing 150 in the headbar 83. Means are provi consists of a bevel 151 through which thesquared portion of shaft 72 slidably extends such gear 151 meshing witha bevel gear secured to the end of a shaft 153 :hivcn by means of asprocket Wheel rom a chain 155 which chain is driven by a sprocket wheel156 on shaft 97.

Resting upon the head bar 83 is a weight 160 having a recess 161arranged to receive the upper end of shaft 72 after the shaft starts itsupward movement, during which movement the shaft picks up the. weightwhich compensates for the added friction of the core in tie mold'afterthe section of pipe is partially completed. A guide ring 162 isprovide-ti for the weight 160 supported on standards mounted on the headbar 83.

'Means are provided for lifting the pan 35 from the mold after thesection of pipe is completed which consists of the following mechanism.The upper end of the mold is provided with a ta ered ring 17 0 whichengages the tapered central opening 171 in the bar 38 when the pan is inlower position. Formed on the blocks 89 the bar 38 are ears 172 and 173.Secured to the ear172 by m ns nuts 174 is a rod 175 which extendsshdably through an ear 176 formed on one end of the crosshead 80. Theupper end of the rod 175 is provided with ahead 177 which is engaged bythe 176 in its upward movement thereby lifting the bar 38 l pan thereon.The lifting of one end of by the rod 175 is equalized on the her end ofthe bar 38 bymea ns ofa pipe 78 rigidly fixed its upper end to an earprovided with a flange 181 which one: the under side of the car 173 asthe pipe is 59 on the crosshead by means of nuts 180,: such pipe beingslidable through the car 173 'on bar 38. The lower end of the pipe 17818 carried upwardly by the cross-head 80 thereby lifting the bar 38.

Freely movable through the pipe 1'78 is a. rod 185 having an upper stopor collar 186 fixed thereon by lllliIlS of a set screw 18? which stop isarranged to be engaged by a coilet spring 188 resting on the ear 179 anda lower stop or collar 1% secured thereto by means of a set screw 191,such collar 190 having a coiledspring 192 seated there on arranged toengage the flange 181 on the pipe as more fully hereinafter described.

- The upper end of rod 185 is connected to one arm 194- of a hell cranklever 105 pivotally mounted on the head bar 83. other 211131196 of thelever 195 is connected by means of a rod 197 with the upper end of anarm 198 fixed at its lower end on a. shaft 199 mounted in a bracket 200,which bracket is supported in the frame of the machine. Secured to theshaft 199 is an 201 the upper end of which forms a fork 202 having pins203 engaging in a circular groove in the clutch member 91.

The bell. crank lever 195 isel'astic'all'y held in the position to whichit maybe moved by i eons of a rod 206, the lower endof u l is beveled toform a blade which seats in a notch 20'? formed in a bar 208 fined tothe frame of the machine. The rod 206 slidably extendsthrough a lug 209on." the arm 196 of the bell crank andis provided with a flange or fixedcollar 210 which engages one end of a coiled spring2i1 on the rod 206.the other end of the springengaging a loose washer 212 \vhich engigesthe under side the lug; 209.
